I definitely should have mentioned that
initially. Yes it works perfectly when directly connected. But I
would like to configure the eth interface to have two addresses,
because we're on a campus, one for network communications to the
outside world, one for the USRP, and use a switch to bring it all
together.
Both the host and the switch support 1 GigE.

Hello
list,
Hopefully this is an appropriate place to ask this question:
I'm trying to connect a host machine to a switch in which a USRP
N210 is also connected. I have configured the host machine's IP
to be static on the 192.168.10.0/24 subnet, and can successfully
ping the N210 at 192.168.10.2. However, when I try to do a
"uhd_usrp_probe", the command simply returns the following:
linux; GNU C++ version
4.6.3; Boost_104601; UHD_003.004.002-152-gdb8f128e
Error: Connection refused
I have also tried to do "uhd_usrp_probe
--args="addr=192.168.10.2" in which case it returns the
following:
linux; GNU C++ version
4.6.3; Boost_104601; UHD_003.004.002-152-gdb8f128e
Error: LookupError: KeyError: No devices found for ----->
Device Address:
addr: 192.168.10.2
My first thought was that it is some kind of firewall issue, so
I issued a "sudo ufw disable", but the results didn't change
(when trying to probe, it returns the above errors, I can still
ping).
According to http://files.ettus.com/uhd_docs/manual/html/usrp2.html#setup-networking,
"When the IP address is not specified, the device discovery
broadcasts UDP packets from each ethernet interface." Which
implies that broadcast UDP packets are not sent when an IP is
specified (which is what I did in my second attempt to probe the
USRP), so I don't think it's a firewall issue.
The switch is a Netgear GS608 which I don't think has "broadcast
storm" control, anyway.
Thanks for any help on the issue.

Simple test. Does it all work when directly connected? (Or
are you using a switch because your host doesn't support 1GiGe?)
